Job description

This is a rare opportunity for a senior networking professional who wants to combine hands-on technical ownership with people leadership and operational responsibility. You'll be the senior owner of a complex on-prem infrastructure estate spanning multiple interconnected sites, taking responsibility for everything from BGP operations, peering, RIPE resources, routing policy, and network resilience through to incident management, governance, documentation standards, and team development.

Rather than stepping into a purely managerial position, this role offers the chance to remain deeply involved in the technology while shaping the wider infrastructure function. You'll work closely with senior technical stakeholders, support carrier-grade network operations, drive operational improvements, and play a key role in network architecture, service continuity, disaster recovery planning, and major customer network projects. It's an excellent opportunity for someone who enjoys ownership, leadership, and solving complex networking challenges in a live production telecoms environment.

You'll be leading from the front in a business where infrastructure sits at the core of service delivery, giving you the chance to influence technical strategy, improve operational maturity, and build a clear pathway toward senior leadership and Chief Technology Officer level progression.

Requirements

  • Proven experience in a senior Infrastructure / Network / Operations leadership role
  • Strong background in carrier-grade or ISP-level networking environments
  • Advanced hands-on experience with BGP operations, traffic engineering, redundancy, and live incident recovery
  • Strong knowledge of MikroTik RouterOS and Juniper Junos
  • Experience managing RIPE resources, IP allocations, and routing policies
  • Proven line management experience, including team leadership, mentoring, and performance management
  • Strong understanding of change control, incident management, root cause analysis, and operational governance
  • Experience managing carrier, supplier, and third-party provider relationships
  • Strong documentation standards across network diagrams, SOPs, runbooks, and DR procedures
  • Excellent communication skills with the ability to work across operations, DevOps, service teams, and senior leadership
  • Telecoms, ISP, or unified communications experience would be highly desirable

Benefits & conditions

  • £80,000 - £100,000 Salary
  • Annual performance bonus linked to uptime and operational KPIs
  • Full ownership of a carrier-grade network estate across multiple interconnected production sites
  • Hands-on leadership role combining technical ownership, team management, and operational strategy
  • Exposure to BGP, peering, RIPE, telecoms platforms, resilience planning, and business-critical network operations
  • Opportunity to lead and shape infrastructure standards, processes, and long-term operational maturity
  • Clear progression pathway to Chief Technology Officer (CTO)
  • Hybrid working with Southampton office and data centre exposure
  • Private medical insurance
  • Company pension
  • 21 Days Holiday + Bank Holidays + Birthday off
  • Cycle to work scheme
  • Health & wellbeing programme
  • On-site parking
  • Company events, employee discounts, and additional office perks
